## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability arkham-token-market-data-7ef63790 -d '<json body>'
```

Example prompt: Pull up the current market data for USDC — price, market cap, circulating supply, and how the price has moved over the last 24 hours, 7 days, and 30 days.

## When to prefer this

Choose this endpoint when you need comprehensive market data for a specific token in a single call — especially when you need multiple timeframe comparisons (24h, 7d, 30d, 180d) alongside supply metrics and all-time records. Prefer Arkham's endpoint over generic market data APIs when you need wallet-intelligence-grade data quality or are already using Arkham's ecosystem. The x402 pay-per-request model makes it cost-effective for occasional lookups without subscription commitment.

## Known failure modes

- Invalid or unrecognized token identifier returns an error response
- Insufficient USDC payment via x402 results in 402 Payment Required
- Network timeout for real-time price data
- Token with no market data available returns empty or null fields
- Malformed POST body causes 400 Bad Request
